TRIPLE-PISTON DEEP-WELL PUMP.

SPECIFICATION forming part of Letters Patent N0. 627,315, dated J u 20,1899.

Appiimiou fiied Augtst'zz, 1898.

To all whom t may con/007121,:

Be it known that LWILLIAM CALVIN VOOD- WARD, a citizen of the UnitedStates, residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented certain new and useful Improvements inTriple-Pis? ton Deep-Well Pumps; and I do declare the following to Vbe afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improved triplepiston pump for deep wells;and the object is to provide a pump of this character whereby bymyimproved construction the efiiciency will be increased by dividing theload in such a manner that with the same expenditure of power a greaterwaterrcapacity will be attained in a given period of time than hasheretofore been the case in pumps employed for this purpose.

To this end the novelty consists in the construction, combination, andarrangement of the device, as will be hereinafter more4 fully described,and particularly pointed out in the claims. p

T-he accompanying drawings show my invention in the best form now knownto me; but many changes in the details might be made within the skill ofa good mechanic without departing from the spirit of my invention as setforth in' the claims at the end of this specification.

The same reference characters indicate the saine parts of the invention.

Figure 1 is a front elevation of my improved pump. Fig. 2 is an enlargedside elevation of the pump-head. Fig. 3 is a similar view of the same,taken at a right angle to that shown in Fig. 2. Fig. 4 is a top planView of the pump-head. Fig. 5 `is an enlarged Vvertical section of thesame. Fig. is a similar view taken at a right angle to that shown inFig. 5. Fig. 7 is a horizontal section on the line 7 7 of Fig. 2. Fig. 8is a similar view Fig. 9 is a similar view taken on the line 9 9 of thesame figure. Fig. is an enlarged vertical section of the pump barrel orcylinder. Fig. 11 is a similar view of the triple-piston rods. Fig. 12is a cross-section on the line 12 12 of Fig. 11.

Serial No. 6895261. (No model.)

Fig. 13 is a diagrammatic View illustrating the relative positions ofthe triple pistons.

1 represents the pump-head, which is rec tangular in form and isprovided on three sides with the horizontal radiating bearing brackets2, 3, 3', and 4, in which are jour naled the shafts 5, 6, 6', and 7.

8 denotes the hood or cover for the head, and it is formed with theintegral bearing caps 9 9 9, by means of which it is removably securedto the alined .bearingbrackets onthe head by the bolts 10 10.Independent bear= ing-caps 11 11 are also secured to the outer ends ofthe bearing-arms to afford the proper protection for the radial shaftsjournaled therein.

12 represents the upper section of the well casing or tube, and it isprovided with the lateral outlet or discharge pipe 13 and with thestuffing-boxes 14 14 14, through which the piston-rods 15, 16, and 17pass.

18 denotes a miter-gear fixed onthe inner end of the shaft 5, and itsface carries a wristpin 19, from which a connecting-rod 20 extendsupwardly to a cross-head 2l, one end of which is formed with aguide-sleeve 22, which encompasses a vertical guide-rod 23, xed in thehood 8, while its other end is formed with a collar 24, whichencompasses the piston-rod 15, to which it is adjustably secured in anysuitable manner, and of course it will be understood that a rotarymotion of the gear 18 will impart a vertical reciprocating movement tothe Vpiston-rod 15. A similar miter-gear is fixed to the inner end ofthe shaft 6 and meshes with the gear 18, and it is providedwith awrist-pin 2G, from which a connecting-rod 27 extends to a similarcrosshead 28, one end of which carries a guidesleeve 29, encompassingthe guide-rod 30, while its opposite end is fixed to the pistonrod 16,as in the iirst instance. A corresponding miter-gear 31 is fixed to theinner end of the shaft 7 and meshes with the gear 25, and from itswrist-pin 32 a connecting-rod 33 extends to the cross-head 34, which, asin the previous instances, has one end encompass'- ing the guide-rod andits other end secured to the piston-rod 7 The back face of theruiter-gear 25 is formed IOO with an annular internal spur-gear 36,which meshes with a pinion 37 on the shaft 6, j ournaled in thebearing-bracket 3 and by means of which the three miter-gears 18, 25,and 3l are driven to simultaneously reciprocate the piston-rods 15, 16,and 17. These piston-rods extend in the order shown in Fig. 12 throughthe Well-tubing 38, holding an approximately triangular position withrelation to each other, but are brought together on a common axis at thepump-cylinder 39 in a manner to be now explained.

The lower end of the piston-rod 15 terminates in a guide-yoke 40, towhich is fixed a depending sleeve 4l, through which the piston-rod 16passes, and also with a parallel guide-orifice, through whichthepiston-rod 17 extends. The lower end of the pistoni-rod 17 terminates ina guide-yoke 42, to which is fixed a depending sleeve 43, whichencompasses the sleeve 41 and the piston-rod 16,' and to the lower endof the rod 16 the piston 44 is fixed, while the piston 45 is fixed tothe end of the sleeve 41, which is a continuation of the piston-rod l5,and the piston 46 is fixed vto the end of the sleeve 43, which is acontinuati'on of the piston-rod 17 .f These pistons 44, 45, and 4G areall similar' in construction, and each is provided with a suitablevalve, which lifts as the piston descends and falls as the piston risesin the manner common to this class of pump-pistons.

By referring to the diagram Fig. 13 the relative course of travel of thepistons will be understood. The circumference of the circle representsthe travel of the wrist pins or cranks, which are set at one hundred andtwenty degrees apart, which would be about ten and one-third (10%)inches from center to center on a twelve (12) inch stroke.

With a single-piston pump of the same stroke the column of Water will beraised twelve (12) inches each revolution, and with a double-piston pumpthe column of water will be raised twenty-four (24) inches, and which isthe present raising limit; but by my arrangement of the triple pistonsone revolution will raise thecolumn of water a height equivalent tothree (3) times the distance between the centers of the crank-pins,(104x 3 31,) which is thirty-one (31) inches, a gain of seven inches inthe lift at each revolution over the best effective work of thedoublepiston pump under the same conditions.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent of the United States, is-

' l. In a lifting-pump, the combination with a single pump-cylinder, atriple set of valved pistons axially mou ntedy Within said cylinder, ofa triple setof intermeshing miter-gears, means for operating said gearsand a series of piston and connecting rods independently connecting eachgear with its respective piston, substantially as and for the purposeset forth.

2. In a lifting-pump, the combination of a single pump-cylinder, atriple set of valved pistons axially mounted Within said cylinder and acorresponding` triple set of intermeshing gear-wheels, independentlyconnected to their respective pistons, and means for simultaneouslyrotating said gear-wheels, so as to independently reciprocate saidpistons,sub stantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Wit- UGSSQS.

WILLIAM CALVIN WOODWARD.
